RSBM 4 in 1 bucket acts as a standard bucket, dozer blade, leveler, and grapple all wrapped into one tool. We engineered this multi-purpose beast to eliminate your attachment swap times and maximize your skid steer’s daily output.
Do you hate stopping your machine every hour to switch from a standard bucket to a grapple? You lose time, you lose momentum, and you lose money. We build the RSBM 4 in 1 bucket to solve this exact problem on modern jobsites.
Our engineers hand-select only the highest quality and toughest skid steer attachments available to ensure you get the job done right. We guarantee every attachment we carry fits modern machines utilizing the universal skid steer quick attach system.
Read this comprehensive guide to master the four core functions of this attachment. I will show you exactly how to leverage our specific models to crush your next project.
What Exactly Are the Four Functions?
You hear the term “4 in 1,” but you need to know exactly how it translates to dirt, concrete, and brush. We combine four distinct tools into a single hydraulic powerhouse.
1. The Standard Material Bucket (Scooping)
Keep the clam closed, and you have a high-capacity loader bucket. You can scoop dirt, gravel, sand, and mulch just like you would with a standard bucket attachment. Our 16mm blade thickness ensures you can push into dense material without bending the cutting edge.
2. The Dozer Blade (Pushing)
Open the clam completely, and you expose the sturdy back blade. You instantly turn your skid steer into a mini bulldozer. You can push heavy dirt piles, clear snow, or backfill trenches with serious force.
3. The Grapple (Clamping)
Open the clam, position it over a load, and bite down. You now have a powerful grapple that easily picks up logs, concrete chunks, and demolition debris. The hydraulic cylinders provide incredible clamping force to secure irregular objects.
4. The Leveler (Grading)
Open the clam slightly and drag the bucket backward across loose soil. The front and rear edges of the open bucket act as a grading tool. You will leave a perfectly smooth, level surface behind your machine.
RSBM 4 in 1 Bucket Specifications and Models
You need hard facts to match an attachment to your machine. We manufacture different skid steer attachments to accomplish major projects efficiently.
Our 4 in 1 buckets come in smooth edge and toothed variations. We designed the smooth edge for precise grading and material handling. We added teeth to the other models to help you break through hard, compacted soil.
Smooth Edge 4 in 1 Bucket Specs
We offer four standard sizes to fit your specific skid steer width and capacity needs:
- 60-inch Model: This bucket features a total length of 990mm, a total width of 1567mm, and a total height of 820mm. It weighs 480kg and holds a storage capacity of 0.4 cubic meters.
- 66-inch Model: We increased the total width to 1717mm while keeping the 990mm length and 820mm height. This unit weighs 510kg and provides a 0.44 cubic meter storage capacity.
- 72-inch Model: You get a total width of 1867mm, a weight of 540kg, and a storage capacity of 0.48 cubic meters. The length and height remain 990mm and 820mm, respectively.

All four of these standard smooth models share an opening distance of 718mm and generate a clamping force of 8390 N. They all operate smoothly at a system pressure of 16-20 Mpa.
Toothed 4 in 1 Bucket Specs
Sometimes you need to rip before you dig. Our toothed models feature a slightly longer profile to accommodate the heavy-duty bucket teeth.
- 60-inch Toothed Model: We build this with a 1020mm total length, 1567mm width, and 820mm height. It weighs 470kg, holds 0.4 cubic meters, and features 6 bucket teeth.
- 66-inch Toothed Model: This bucket gives you a 1717mm width and weighs 500kg. It holds 0.44 cubic meters and utilizes 7 bucket teeth for maximum penetration.
- 72-inch Toothed Model: We expanded the width to 1867mm and the weight to 530kg. You get 0.48 cubic meters of capacity and 7 bucket teeth.
- 84-inch Toothed Model: The ultimate ripping tool features a 2167mm width and weighs 590kg. It carries 0.54 cubic meters of material and also sports 7 bucket teeth.
Just like the smooth variants, these toothed buckets boast a 718mm opening distance, 8390 N of clamping force, and require 16-20 Mpa of system pressure.
The Heavy-Duty 84-inch 4 in 1 Bucket
If you run a massive machine on a brutal demolition site, you need our specialized high-capacity model. We built a heavy-duty 84-inch variant specifically for extreme environments.
This massive bucket measures 1200mm in total length, 2060mm in total width, and 1050mm in total height. It weighs a solid 950kg and delivers a massive 1.1 cubic meter storage capacity. We increased the opening distance to 850mm and achieved an 80-degree opening angle. Most importantly, we upgraded the clamping force to an incredible 14390 N.

How to Master the 4 in 1 Bucket on the Jobsite
You own the tool; now you need to know how to maximize its potential. I see operators limit themselves by treating this attachment like a basic dirt scoop. Follow these operational steps to dominate your jobsite.
Step 1: Execute the Perfect Clamp
Open the clam jaws completely using your auxiliary hydraulic controls. Drive your skid steer forward until the rear blade makes contact with the log, pipe, or debris pile. Close the clam jaws firmly, utilizing the 8390 N clamping force to lock the material in place. Tilt the bucket back, keep your load low to the ground, and transport the debris safely.
Step 2: Push and Backfill Like a Pro
Dump any material out of the bucket and open the clam all the way. You now expose the straight dozer edge. Lower your boom until the cutting edge lightly touches the ground. Drive forward to push dirt into a trench or push brush into a burn pile. The 16mm blade thickness handles the heavy impact without warping.
Step 3: Grade and Level Rough Terrain
Scoop a small amount of loose dirt into the bucket. Open the clam about three to five inches. Tilt the bucket slightly downward and drive your machine in reverse. The dirt will slowly spill out of the gap while the front and rear cutting edges smear and flatten the soil. You will create a perfectly graded surface ready for seed or sod.
Step 4: Dig and Excavate
Keep the clam completely closed. Approach your dirt pile or trench line. Lower the bucket, tilt the leading edge down, and drive forward to penetrate the earth. If you deal with hard clay, equip the toothed 4 in 1 bucket to let the 7 bucket teeth shatter the hardpan first. Curl the bucket back to capture the 0.54 cubic meters of soil and lift the boom to load your dump truck.
Pro-Tips from an RSBM Engineer
I spend every day evaluating how attachments perform in the mud and dirt. I want you to get the longest possible lifespan out of your investment. Follow these technical guidelines.
Lubricate Every Pivot Point You expose the clam hinges and hydraulic cylinder pins to extreme friction and dust. Grease every single zerk fitting on the bucket before you start your morning shift. Fresh grease pushes out the abrasive grit that destroys metal pins over time.
Manage Your System Pressure Our 4 in 1 buckets operate optimally between 16 and 20 Mpa of system pressure. Do not bypass your machine’s pressure relief valves to force more power into the clamp. You will blow hydraulic seals and damage the cylinders. Trust the engineered 8390 N clamping force; it easily handles standard jobsite debris.
Use the Right Edge for the Right Job Do not use a smooth edge bucket to pry up thick asphalt. You will prematurely wear the cutting edge. Choose the toothed 66-inch or 72-inch model if your primary application involves breaking hard ground. Save the smooth edge for your final grading, snow removal, and loose material handling.
Inspect Hydraulic Lines Daily The clamping motion requires flexible hydraulic hoses that move with the clam shell. Inspect these hoses every day for signs of abrasion, pinching, or weeping fluid. Replace a worn hose before it bursts and causes an environmental spill on your client’s property.
Frequently Asked Questions
What happens if I try to lift more than the storage capacity? You risk tipping your skid steer forward or blowing a hydraulic line. Always respect the 0.54 cubic meter maximum storage capacity on our standard 84-inch model. If you require more volume, upgrade to the heavy-duty model which handles 1.1 cubic meters.
Does the 4 in 1 bucket replace the need for a dedicated grapple? It replaces a dedicated grapple for 90% of general construction and landscaping tasks. However, if you run a full-time forestry or scrap yard operation, a dedicated skeleton grapple allows more visibility and lets loose dirt fall through the tines.
Will an RSBM 4 in 1 bucket fit my older Caterpillar skid steer? Yes. Our skid steer attachments are compatible with Caterpillar, Bobcat, John Deere, and 99% of skid steers using the universal quick attach system.
How thick is the cutting edge on these buckets? We build all our standard 4 in 1 buckets with a 16mm blade thickness. This specification ensures long-term wear resistance against concrete and rocky soil.
Do you offer a warranty on the 4 in 1 bucket? Yes, we confidently offer a 6-month warranty on our attachments. We dedicate ourselves to manufacturing high-quality tools that survive harsh environments.
